Enclosure REQUEST FOR ADDITIONAL INFORMATION STEAM GENERATOR TUBE INSERVICE INSPECTION REPORTS FOR THE 2007 REFUELING OUTAGE ENTERGY NUCLEAR OPERATIONS, INC.
INDIAN POINT NUCLEAR GENERATING UNIT NO. 3 DOCKET NO. 50-286 In a letter dated July 19, 2007 (ADAMS Accession No. ML072120612), Entergy Nuclear Operations, Inc. (Entergy), submitted information pertaining to their 2007 steam generator (SG) tube inspections at the Indian Point Nuclear Generating Unit No. 3. These inspections were performed during the fourteenth refueling outage of Unit 3.
The Nuclear Regulatory Commission staff has reviewed the information Entergy provided and determined that the following additional information is required in order to complete the evaluation:
- 1.
In Section 6.0, you indicated that a loose part was detected during a secondary side visual exam. Please provide the scope and results of any other secondary side inspections (including foreign object search and retrieval) performed during the 2007 outage.
- 2.
+PointTM inspections were performed at the top of the tubesheet (TTS) in both the hot leg and cold leg to detect possible loose parts (PLPs). Please discuss whether there were any PLPs found by rotating probe that were not detected by the bobbin probe. In addition, discuss whether these PLPs were confirmed as loose parts via visual inspection. Please discuss whether PLPs were detected at any other locations (i.e., other than the TTS) and discuss how these were dispositioned.
- 3.
During the 2003 outage, the U-bend region of three tubes in SG 3 could not be inspected with a 0.700-inch diameter bobbin probe. Please discuss whether these three tubes were inspected this outage. In addition, please discuss whether any other tubes were found that would not pass the nominal sized probe, and whether the restrictions are becoming more severe with time.
- 4.
During the 1997 outage, possible indications of erosion-corrosion were identified in two J-tube welds in SG 4. If the steam generator internals in SG 4 were inspected in the 2007 outage, please discuss the inspection results including the results, if any, from the inspection of the two J-tube welds that had possible indications of erosion-corrosion in 1997.
- 5.
During the 2003 outage, inspections revealed one tube that was classified by the licensee as having a trackable anomaly. This tube was not considered to be flaw-like, but was added to the sample population for the next inspection of that SG. In addition to the trackable anomaly, a free span bobbin indication was identified in one tube in 1997, in SG 4 (Row 8 Column 21). During the 1997 outage, a rotating probe inspection of this location revealed the presence of a small ding. No inspections were required to be performed on this tube and the licensee did not consider it necessary to inspect this tube as part of the sample inspection performed during RFO 12 in 2003 (i.e., the licensee did not consider it necessary to inspect this tube until its regularly scheduled inspection during RFO 14). Please discuss whether these indications (i.e., the trackable anomaly and the freespan indication) were inspected in the 2007 outage, and if so, include the inspection results.
- 6.
Since the 2003 inspection, there was at least one chemical excursion that exceeded Action Level 1 of the Electric Power Research Institutes Secondary Buffer Chemistry Guidelines. Please discuss whether any deleterious affects were discovered as a result of this chemical excursion (or other chemical excursions) including any abnormal deposit buildup.
- 7.
For future reference, please provide the cumulative effective full power months of operation for each refueling outage, or SG tube inspection outage, since the steam generators were installed.
- 8.
Please confirm that the straight sections of 100 percent of the row one and row two tubes have been inspected since the first in-service inspection of your SGs.
